An American evangelical Christian leader is calling for a boycott of ex-Pink Floyd rock star Roger Waters’ Miami concert on Thursday.

“Roger Waters is a flagrant antisemite,” Laurie Cardoza-Moore — president of the pro-Israel group Proclaiming Justice to the Nations — said on Wednesday. “All Christians, Jews and people of conscience should publicly condemn him.”

“Everybody should do what they can to voice their concern that this antisemite is spewing his despicable brand of hatred in the Sunshine State,” she continued. “Contact your local lawmakers, picket the concert, speak out on social media, but whatever you do, do not remain silent.”

In recent years, Waters, 73, has spoken out against Israel’s West Bank security barrier and become a vocal proponent of the boycott, divestment and sanctions (BDS) movement.

Also on Wednesday, the Greater Miami Jewish Federation placed on ad on the Miami Herald homepage with a message for Waters, whose concert will take place at the American Airlines Arena. “Anti-Semitism and hatred are not welcome in Miami,” it said.
